PT8.S01.Q20 - Which one of the answer choices...

carrot-celery-onion

I'd like to discuss this question, as it seems there's no explanation available on 7sage. That should be rectified, as this is a very tricky and unconventional question which therefore warrants a thorough explanation.

In the mean time, I'll give it a shot:

The question stem here seems to be, "Which one of the answer choices will fully justify (or make must be true) one of the two question options, definitively?"

It's an odd question in that it doesn't ask you to justify approach A or approach B -- it instead asks you to identify a principle that will make EITHER ONE OF A or B must be true, whilst simultanouesly making either B or A must be false -- all based on the stimulus information.

So far as I can tell, (B) is the only one that does this with that level of certainty. It says that, based on the stim information available, the renovation was correct while the demolition camp was incorrect.

Unusual, difficult question.
